Once we can go inside the container, create a project with the start command.

As Ionic is asked whether to use versions 3, 4 and 4 version, enter y for yes

/usr/src/app # ionic start
[INFO] You are about to create an Ionic 3 app. Would you like to try the release candidate for Ionic 4?
Ionic 4 uses the power of the modern Web and embraces the Angular CLI and Angular Router to bring you the best
version of Ionic ever. See our blog announcement[1] and documentation[2] for more information. We'd love to hear
your feedback on our latest version!

? Try Ionic 4? (y/N)

Next the project name will be asked.

In this example, enter sample.

Every great app needs a name! 😍

the first argument to ionic start.
? Project name:

Next, select the type of template by positioning the cursor.

? Project name: sample
Let's pick the perfect starter template! 💪
Starter templates are ready-to-go Ionic apps that come packed with everything you need to build your app. To bypass this
prompt next time, supply template, the second argument to ionic start.
? Starter template:
blank | A blank starter project
❯ sidemenu | A starting project with a side menu with navigation in the content area
tabs | A starting project with a simple tabbed interface

When you select a template, installation of necessary modules is started automatically.

(It is so convenent right?)

Installation takes several minutes.

When installation completes, you are asked whether you want to install the Appflow SDK.
